For a power distribution system with distributed generation (DG) units, its fault current and induced overvoltage under abnormal conditions should be taken into account seriously. In consideration that applying superconducting fault current limiter (SFCL) may be a feasible solution, in this paper, the effects of a voltage compensation type active SFCL on them are studied through theoretical derivation and simulation. The active SFCL is composed of an air-core superconducting transformer and a PWM converter. The magnetic field in the air-core can be con-trolled by adjusting the converters output current, and then the active SFCLs equivalent impedance can be regulated for current-limitation and possible overvoltage suppression. During the study process, in view of the changes in the locations of the DG units connected to the system, the DG units injection capacities and the fault positions, the active SFCLs current-limiting and overvoltage-suppressing characteristics are both simulated in MATLAB. The simulation results show that the active SFCL can play an obvious role in restraining the fault current and overvoltage, and it can contribute to avoiding damage on the relevant distribution equipment and improve the systems safety and reliability.

In addition to columns, beams, slab RCC structures are having vertical plates or walls called the shear walls. We are calling them shear walls as they are resisting large amount of shear because of lateral loads on the RCC structure. Thus, shear deformation does not dominate the RC wall failures. Shear walls are a type of wide beams that carry the seismic forces or loads to the base or foundation. It can also act like a cantilever to oppose the lateral loads without or in presence of the frames. The vertical elements of the lateral load resisting system are the Shear walls. We are constructing the shear walls to reduce the effect of the lateral loads on a tall structure. Shear walls are constructed in the residential as well as the commercial buildings based on the requirements to form a box type structure to resist the lateral loads. Thus after proper design and construction shear walls are ready to resist the lateral loads acting on the structure bearing sufficient strength and stiffness to resist these loads. The Shear walls which are constructed in the structure not only resist the vertical loads and its self weight but also the lateral loads due to winds, earthquake and sway moments. The shear walls are placed at such positions and angles such that it has a considerable affect on the lateral loads. Therefore, shear walls are best suited for the structure in the resistance of the lateral loads. Shear walls has to resist many forces acting on it such as the pull of the wind forces, the shear forces which pushes the walls, etc., Different types and shapes of shear walls are constructed in the structure according to the lateral load resistance design requirements, hence gaining the three dimensional stability.

Switched mode power supplies (SMPSs) are used for powering up different parts in a personal computer by developing multiple dc voltages from a single-phase ac voltage. Normally, a bridge rectifier (BR) followed by a filter capacitor is used at the front end of these SMPSs. BR causes significant reduction in the power quality. This thesis deals with the design, analysis, simulation and development of a power-factor-correction (PFC) multiple output switched-mode power supply (SMPS) using a bridgeless buck–boost converter at the front end. Single-phase ac supply is fed to a pair of back-to-back-connected buck–boost converters to eliminate the diode bridge rectifier, which results in reduction of conduction losses and power quality improvement at the front end. The operation of the bridgeless buck–boost converter in discontinuous conduction mode ensures inherent PFC operation and reduces complexity in control. For providing isolation and multiple output a forward converter (FWDC) with active clamping circuit is proposed. Simulation of the proposed converter is done using MATLAB R2014a. Finally an experimental set up of 30W is set up in laboratory and verified the feasibility of the proposed topology.

Present study was conducted to evaluate the hydrolysis efficiency of three different white-rot basidiomycete fungi including Pleurotus florida (PF), Pleurotus sajor-caju (PS) and Pleurotus eryngii (PE). Under this study, digestion of groundnut powder with reference to enzyme yield, release of free sugar, and loss in dry matter were investigaed. Initially these strains were cultivated under submerged conditions with groundnut husk substrate for the production of enzymes. Pleurotus florida comparatively produced its highest CMCase (345 UL-1), β-glucosidase (69 UL-1), β-xylosidase (41 UL-1) and xylanase (277 UL-1) activity under the conditions of submerged fermentation. Furthermore, these enzymes produced were used to check in vitro degradability of groundnut powder. Direct enzymetic treatment of groundnut powder using mono extracts (PF, PS, & PE) and mixed enzyme extract (PF+PS, PF+PE, PS+PE and PF+PS+PE) combinations significantly hydrolyzed the substrate. These enzyme extracts from all three fungi resulted significant dry matter loss and free sugar yield. In consequence, the highest 8.2% dry matter loss was recorded with PF+PS+PE mixed extract. In addition, treatment with PF+PS+PE extract resulted highest 448 mg/g sugar content from the hydrolysis of groundnut husk powder. Therefore, based on the findings of the study; use of enzyme extracts from the Pleurotus florida is recomended for the saccharification of lignocelloses at large scale.

Mobile ad-hoc networks allow easy, fast and inexpensive network operation. An ad-hoc network is a collection of mobile nodes that dynamically form a temporary network and are infrastructure less. Nodes of the network communicate with each other directly or through intermediate nodes. Routing protocols are requisite to discover a best possible path between source and destination node. Mobile Ad-hoc Networks have many security vulnerabilities due to which ad-hoc networks are isolated to attacks of the malicious nodes. One of these attacks is the Black Hole attack against network veracity. During this attack, nodes absorb all data packets in the network. And the data packets do not reach to the destination which results loss of data. This paper compares the corresponding simulation result in Ns2.35 and demonstrates that our technique not only prevents black /gray hole but also improves performance.
